Visibility IV / V
Hasamäki had the last cannoning day of the winter and fortunately also finally sunshine. 12-15 degrees below zero, so no very strange halos were born. In calm weather, a cloud of fog spread over a distance of more than 10 km and the side suns and the lower sun flickering in the crystals shone bright in many places. The stacks revealed the Schulthesses, and the drone picked up the side suns from above in addition to the lower sun.
The main picture is a drone image from the top of a 120 meter dense fog cloud. Second, a compilation of drone images from different heights from about 70-120 meters every 10-20 meters. The location of these was 3 km from Hasamäe. In Figures 3-4, a stack of 30 images, treated differently, closer to Hasamäki. Pictures 5-8 have been taken from the ice of Lake Jukajärvi at a distance of 9 km from Hasamäki. Figure 5 is a single view of the halos and Figure 6 is a stack of 30 images treated (usm-bg-usm) from the same situation. Figure 7 from the same place from the drone at 120 meters and in the last picture the glow of the lower sun from the same place.
